About this water

The Boulzane flows through the Fenouillèdes basin where Pyrenean stone creates clear water and good trout. AAPPMA-managed with both fly-only and general beats. No-kill stretch available. Wild brown trout respond to seasonal patterns — Baetis in spring, sedges and mayflies through summer. Spate character after rainfall. Check local regulations for parcours requirements.
